Our telemetry data is from the Keck II AO system running in closed loop on the night of 04-20-2019, previously published in Jensen-Clem (2019)[1]}. It consists of 120000 time steps of data (taken at \(\sim 1.7\) ms intervals[2]}) in the form of DM commands and near-IR pyramid wavefront sensor[3]} (installed in Keck II as part of the KPIC upgrade[4]}) phase measurements in units of volts. Keck II is a 10 meter telescope, with a 21 by 21 actuator deformable mirror (we use the pyramid wavefront sensor's 21 by 21 reconstructed residuals to match.)
